Corazonin Stimulates Ecdysteroid Synthesis during the Molting Process of the Swimming Crab, Portunus trituberculatus [PDF]
BiologyThe neuropeptide corazonin (Crz) exerts diverse physiological effects in insects, yet its role in crustaceans remains elusive. The abundant expression of Crz receptor (CrzR) in the Y-organs of several crustaceans suggests a potential involvement of Crz ...

Sex-Specific Response to Predator Auditory Cues in Asian Corn Borer (<i>Ostrinia furnacalis</i>). [PDF]
Ecol EvolFemales downregulate more DEGs; males upregulate under predation risk. Males boost ecdysteroid; females reduce fecundity under bat ultrasound. Female O. furnacalis reacted more strongly to auditory cues of bats than males. ABSTRACT Predation risk has profound effects on prey from phenotype to gene expression.

Mapping molluscan endocrinology: a systematic and critical appraisal. [PDF]
Biol Rev Camb Philos SocABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Resource Availability Modulates Gene Expression Across Life Stages in a Migratory Butterfly. [PDF]
Mol EcolABSTRACT Natural populations are in constant need of balancing resource allocation to compensate for seasonal environmental variation. In many insects, a well‐established trade‐off between migration and reproduction exists. While this trade‐off has been characterised phenotypically for decades, the underlying regulatory pathways are poorly understood ...

Identification of ecdysteroids and ecdysteroidogenic genes in dragonflies and damselflies [PDF]
Scientific ReportsEcdysteroids are critical in regulating biological processes such as ecdysis, metamorphosis, embryogenesis, and reproduction in insects. Nevertheless, the ecdysteroid repertoire and expression patterns of their synthesis genes in Odonata (dragonflies and

Upregulation of Insulin and Ecdysone Signaling in Relation to Diapause Termination in Bombyx mori Eggs Exposed to 5 °C [PDF]
InsectsIn the present study, we investigated the possible correlation between insulin/ecdysone signaling and chilling-induced egg diapause termination in Bombyx mori.

Encyclopedia, 2021 Ecdysteroid: member of a class of polyhydroxylated steroids found in invertebrate animals (zooecdysteroids; moulting hormones), plants (phytoecdysteroids) and fungi (mycoecdysteroids). Over 500 structural analogues are currently known. Biosynthetically, they derive from C27-, C28- or C29-sterols.

Parasites & Vectors, 2021 Background It is well established that ecdysteroid hormones play an important role in arthropod development and reproduction, mediated by ecdysteroid receptors. Ticks are obligate hematophagous arthropods and vectors of pathogens.
